In yesterday's (Thursday 3.8.) batch of updated packages, there are 4 cups-related update packages. Several users have reported serious problems (no print, or white page instead of printed content) after installing these packages - see https://bugs.mageia.org/show_bug.cgi?id=21444.

In case you have not yet installed these packages, you better wait until this has been clarified (so far, a safe and easy method for reverting to the precedent version has not been mentioned). It is not yet clear whether the culprit is one of the cups packages themselves, or one of the other packages of that batch.

PS: a workaround for downgrading to the previous situation now exists; quoting from the mageia discuss list:

Or actually just downgrade qpdf, cups itself is fine:

urpmi --searchmedia "Release" --downgrade lib64qpdf17

(if you have qpdf, qpdf-doc or lib64qpdf-devel installed, downgradethose too for consistency)

I quoted the "official opinion": only the downgrade of the package lib64qpdf17 is needed (and works for me). There is a minority of comments that claim that also the 4 cups packages need to be downgraded - you might give that a try: (as root) do

Sorry for not offering more than quotes of opinions and guesses what to try as a workaround - the precise logic of this bug still needs to be clarified. And, did you make sure that you did not accidentally get installed a new upgrade of the just downgraded package? The best way to prevent this is to add, for each package to exclude from upgrading, a line into your /etc/urpmi/skip.list ( /lib64qpdf17/ for instance) - dont forget to remove these lines once things are OK again!

If your problem is solid, please help by documenting this (the type of your printer and the fact that the problem persists if only lib64qpdf17 is downgraded) in a short comment to https://bugs.mageia.org/show_bug.cgi?id=21444 !

CUPS regularly ships updates which are plain broken,[...] It has happened so often that I have given up even trying to report the errors. I don't know why they do this [...]There are two main errors:[...]• In the CUPS-supplied ps* filters there is some bug which causes the "filter failed" error message.This has been fixed a couple of times, but repeatedly gets unfixed somehow.

So... CUPS team did it again ?

From Mandrake 5 to Mandriva until the end, Linux Mint 17, and now Mageia 5, 6

are available for upgrading in core/update-testing, tomorrow they should have landed in the update repositories and trigger the ordinary update process. Dont forget to also upgrade lib(64)qpdf17 now in case you had done a downgrade.

Thanks for the tip. No updates have been available for the past few days, so I tried the "downgrade" mentioned at the start of this thread. My Epson ET-2550 is now printing again....And the crowd went wild.

No matter what I tried, could not get cups to print to network printerI have a Samsung ML1640 connected to windows 10 USB port.I am able to print from: Windows 10 local printer Windows XP on the same LAN Other than Mageia 6 linux distribution using CUPSNo success from Mageia 64b, either before or after downgrade. I could have printed with Mageia 5 before I upgraded to 6Any clue??JJF
